GAS BURNER. APPLICATION FILED MAR-J 1918- 1 substantiall PATENT OFFICE.

MARTIN A. MOORE-0F TOPEKA, KANSAS;

GAS-BURNER.

' Application filed March 9,

To all whom it may concern:

Be it known that I, MARTIN A. MOORE, a citizen of the United States,residing at Topeka in the county of Shawnee and State of Kansas, haveinvented certain new and useful Improvements in Gas- Burners, of whichthe following is a specification. 7

This invention relates to improvements in gas burners, more especiallyof the heater Ihe invention has for its object to provide for the mixingof an increased amount or supply of air or oxygen with the supply of gasand accordingly cause a greater or more extended flame or heat-unit. Itis a further characteristic of the invention that, when the gas is onlyabout half up'to standard, the flame will be brought up above the burnerand will supply as much heat as if the gas were of standard quality. Theinvention consists of the detailed structural features and arrangementthereof as hereinafter more fully set forth and efined in the appendedclaim.

In the accompanying drawing is illustrated the preferred embodiment ofmy invention, and in which drawings gigure 1 is a plan view of myinvention, an

Fig. 2 is a sectional elevation of the same.

In carrying out my invention, I form the burner 1, which as usual, has acontinuous plurality of underneath notch-formed airinlets 2 in its base.Said burner has a crowning upper flame surface 3, the same slopingsymmetrically along its lateral portion, as at 4, downwardly from acentral upper opening or crater 5, which constitutes the mamflame-orifice and which will be later further referred to.

In the sloping lateral portion of the burner is provided alsoflame-orifices 6., pref- Specification of Letters Patent.

Patented J uly 13, 1920. 1918. Serial No. 221,453.

erably oblong in outline and preferably four in number, and atsubstantially equal intervals apart and relatively distant from thecentral orifice, this orifice with the described cooperating group offlame-orifices, providing for producing an extended or broad flame, andwhich accordingly results in a great or powerful heat-unit.which is theend, of course, greatly or much sought, especially in this type ofheat-generating gas burners. It is especially emphasized that thecentral or crater flame orifice 5, is of greatly enlarged flame emittingcapacity, being much larger than the lateral flameemitting orifices 6,the central and lateral fiame'orifices being both also much. larger thanthose provided ordinarily in gas burners. I have found by practicalexperience with this burner that, as above stated, I am enabled to mixan increased amount of air or oxygen with the supply of gas andaccordingly cause a greater or more extended flame or heat-unit.

I claim A burner of the class described c0mpris ing a lower cylindricalportion and an upper portion of frusto conical, shape, said cylindricalportion having notches in its lower edge and the frusto conical portionhaving a circular opening in its top and four oblong openings midwayitsends, the oblong openings being spaced a quarter of a circle fromeach other, an arm concentrically arranged in relation to the centralopening and said oblong openings and the central opening having inwardlyflaring walls.

In testimony whereof I afiix my signature in the presence of twowitnesses.
